== Scalers ==

Three mostly-used scaler channels are I_start, I_middle and I_final. They are [[wikipedia:Ionization chamber|ion-chambers]] monitoring beam intensity at different locations along the beam:
* I_start: after the defelecting mirror, before the W-slits (a pair of slits defining the aperture of the K-B mirrors).
* I_middle: after the W-slits, before the K-B mirror.
* I_final: after the K-B mirrors and the sample.

* Amplifiers for individual ion chambers
** 34ide main panel -> "scalers & amps" (near bottom right corner) -> "Ic_*** amp"

== Area Detectors ==
''See Also: [[34ID-E Coordinate Systems#Detector Coordinates]]''

There are three permanently-installed area detectors at 34ID-E. They are amorphous-silicon detectors made by Perkin-Elmer. The three detectors are code-named Yellow, Orange, and Purple.
* Orange detector: placed on the top; 2048 &times; 2048 pixels; controlled by computer "s34pe2"
* Yellow detector: placed on the outboard side; 1024 &times; 1024 pixels; controlled by computer "ornlpe1"
* Purple detector: placed on the inboard side;  1024 &times; 1024 pixels; controlled by computer "ornlpe3"
Pixel sizes are 200 &mu;m &times; 200 &mu;m for all three detectors.

=== Detectors in the forward direction ===

Ion chamber I_final is the only detector placed in the forward direction (downstream after the sample) in our regular setup. It can be removed if necessary to accommodate other detectors such as a CCD or Pilatus in the forward direction on the table. One may borrow them from the [http://www.aps.anl.gov/Xray_Science_Division/Detectors/Detector_Pool/ APS Detector Pool].
